This invention relates to an improved slide for extension tables.

An object of this invention is to provide an improved metal slide to connect the sections of an extension bar of a table which will not swell or Warp to prevent longitudinal movement of the bar; which is provided with improved connecting means to insure a rigid connection between the sections in any position; and which is of such size that various numbers thereof may be used depending on the size of the bar, thereby providing a wide range of utility.

Other objects and advantages of the invention will become apparent from the following specification of which the drawing forms a part, and wherein:-

Figure 1 is a cross sectional view on the line I-I of Figure 2,

Figure 2 is a top plan view of an extension bar connected by the slides,

Figure 3 is a cross sectional view on the line 3-3 of Figure 2, and

Figure 4 is an enlarged perspective view of one of the slides.

Referring more particularly to the drawing wherein like reference characters designate like or corresponding parts throughout, I0 designates a table extension bar formed of the sections II, I2 and I3 each of which is provided in its abutting face or faces with longitudinal grooves I4 spaced at intervals by the tongues I5 which are adapted to extend into the groove of the abutting face thereby restricting the movement of the sections to the distance between the tongues I5. Tongues I5 are substanti-ally the same length as the slide I'I. The tongues I5 of the abutting faces of any two of the sections project in opposite directions and are normally arranged in staggered relationship at equal distances from each other, or in other words, the tongues I5 which project in one direction are normally alined, as in Figure 1, and the tongues I5 which project in the opposite direction are likewisek normally alined, as in Figure 3. Extending'diagonally and opening into the abutting faces of sections II, I2 and I3 are slots I6 by which the sections are connected as will be hereinafter explained.

Referring especially to Figure 4 the table slide I1 comprises a channel shaped portion I8 which ts onto the tongue I5 and is secured by countersunk fasteners I9 which extend through the intermediate part. of channel portion I8 and into the section of which the tongue I5 forms a part. Projecting at acute angles from the sides of said channel portion I8 are flanges 20. A cut-out portion 2I is formed between the ends of the flanges 20 and is bent outwardly to provide a tongue which projects at an obtuse angle from the sides of the channel portion I8 thus form- 5 ing a flange 20 on each side of tongue 2|.

From the foregoing it will be obvious that when the channel portion I8 of one of the slides I'I is attached by the fastenings I9 to a tongue I5 of one of the sections, it will extend into the 10 groove I4 in the abutting face of the adjoining section. The flanges 20 will fit into the slots I6 above and beneath the groove I4 of the section into which portion I8 extends, thereby rigidly connecting the sections in slidable rela- 15 tionship. The tongue 2l will project into the slots I6 of the section to which slide I 'I is secured to more securely attach the slide II.

Only one slide II has been described; it is to be understood that all of the slides II are at- 20 tached in a like manner. Since tongues I5 project in opposite directions in alternate relationship between the abutting faces of the sections II, I2 and I3, the slides I'I between the abutting faces will likewise face in opposite directions 25 alternately to correspond. From this it will be seen that the distance which the sections II, I2 and I3 can move relatively to each other to open the table is limited by the space between the slides I'I. Studs 22 are provid-ed in the sec- 30 tions adjacent one end of bar Ill to form stops to prevent the sections moving past a closed position which might tend to damage the abuttng edges of the table top.

It is to be understood that only a preferred 35 embodiment of the invention has been shown, the right being expressly reserved to make such changes and modifications as will not depart from the spirit and scope of the invention as hereinafter claimed.

I claim as my invention:-

1. In combination with an extension bar provided with tongue and groove portions and diagonally extending longitudinal slots; a table slide comprising a channel shaped porton adapted 45 to engage the tongue of one section of said bar, flanges projecting from the sides of said channel shaped portion to slidably engage the slots in the adjacent section, and tongues projecting from the sides of said channel portion to engage the 50 slots in the section to which said slide is secured.

2. In combination with an extension bar formed of a plurality of sections slidably mounted relatively to each other and having alined grooves in their abutting faces, tongues arranged in 55 i spaced alternate relationship in the grooves of said sections, table slides each provided with a channel shaped portion to be secured to one of said tongues and to project and be slidably mounted in the groove of the abutting section, and means projecting from each of said channel shaped portions to slidably connect with said abutting section, said slides being arranged at spaced intervals between the abutting sides of said sections and faced alternately in the opposite direction.

3. In combination with a table extension bar formed of a plurality of slidable sections, said sections being provided with grooves in their abutting faces, tongues extending from said sections between the ends of said grooves and arranged to project alternately in the opposite direction for engagement with the groove of the abutting section, and said sections being provided with diagonally extending slots opening into the abutting faces; table slides secured to said tongues and facing alternately in opposite directions, and means projecting from said slides to extend and be slidably mounted in the adjacent slots of the abutting sections to connect said sections.

4. A table extension bar slide comprising a bar formed of a plurality of sections having abutting faces, said faces being provided with longitudinal grooves and diagonally disposed slots opening into said faces, and tongues formed in said faces in alternate spaced relationship lto Aproject, into the groove of the abutting face; slides comprising channel shaped portions shaped to t said tongues and to extend into the adjacent grooves, flanges projecting from said channel portion to slidably engage the slots of the abutting section, and tongues extending from said channel portion to engage the slots of the section on which said slide is mounted to hold it in position, said slides being faced alternately between said sections thereby limiting the movement of the sections to the distance of the space between the slides.
